The Phase IV Bevill proposal (61 FR 2338; 1/25/96) would clarify the distinction between in-process materials and wastes in the Bevill exemption for mining and mineral processing wastes. The notice proposes retaining the TCLP and the classification of several wastes, including five smelting wastes that were previously lifted, iron chloride waste acid, and wastes from lightweight aggregate production. The notice proposes to exclude processed scrap metal and shredded circuit boards that are destined for metal recovery and managed in containers. The notice proposes to significantly reduce the land disposal restrictions (LDR) paperwork requirements that apply to hazardous waste generally (SEE ALSO: Phase IV Final Rule, 63 FR 28556; 5/26/98).
